摘要
在含干摩擦特性的动态系统的数字仿真中，采用理想干摩擦力模型常常会出现数值不稳定而导致错误的计算结果。本文分析了产生数值不稳定的条件，据此提出了一个稳定性良好的干摩擦力数值计算模型，通过仿真表明了算法的有效性。
In digital simulation of dynamic system with dry friction forces, numerical instability always occurs and leads to incorrect results when the theoretical model of dry friction is used.This paper finds the conditions under which numerical instability occurs, and presents a numerical model of dry friction forces,which is proved to bestable and effective through digital simulations.
